How to install a heat resource plug-in?

[zzxwill]

Hi Tim, as I know, your plug-in could be installed via "sudo python setup.py install --install-purelib=/usr/lib/heat". But I don't have a setup.py in my plugin. Here is my question about installing my heat resource plug-in. Could you please help take a look at them? Thanks.

1. Should the plug-in under /usr/lib/heat be copied to /usr/lib/python2.6/site-packages/cms_heat_plugin after heat service is restarted.

2. Why openstack-heat-engine failed to restart after I put my plug-in "heat_plugin" under /usr/lib/heat and restarting heat service?
